HARDEN PALMER, OF EVERETT, MASSACHUSETTS.

SHUTTER-FWORKER.

F ECEFIG ATION forming part of Letters Patent No. 32 dated August 11,1885- Application filed November 17, 1884. (No model.)

To all whom it may concern:

Be it known that I, HARDEN PALMER, of Everett, county of Middlesex, andState of Massachusetts, have invented an Improvement inShutter-Operators, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing llke parts.

This invention relates to shutter-workers; and it has for its object toimprove, simplify, and cheapenthc construction.

The invention consists in the construction hereinafter particularly described,and pointed out in the claim.' Y

Figure 1 represents in elevation a window having usual blinds orshutters provided with my improved shutter-operator; Fig. 2, a sectionof Fig. 1 on the dotted line 0: 90; Fig. 3, a section of theshutter-operator, taken on the dotted lin'ey 3 Fig. 4, the shaft beingshown in elevation. Fig. 4 shows in elevation the bent lever and itsoperating mechanism as viewed from the dotted line .2 2, Fig. 3, thebent lever being, however, turned to the right.

The window-jamb A, sill B, and blinds or shutters O, pivoted to thejarnb A by hinges D,

are and may be of any ordinary construction, so need not be hereindescribed.

The box or casing a, of sufficient size to contain the operating parts,is secured, as shown, in this instance beneath the sill B.

One end of the rod or shaft 12, having the worm (1 attached to it, hasits bearings at2 in the box a, the said rod being of sufficient lengthto extend entirely through the side of the building,.such rod at itsinner side, within the building, being provided with a handle, 1/, andknob 1).

One end of the bent lever c, which is employed to operate the shutter,is extended through the worm-gear e, placed in the case a at rightangles to the worm, and the said lever at each end of the worm-geartakes hearing in the said case. The upturned outer end of the lever centers a slot in the lower end of the blind or shutter or in a metalplate connected therewith.

To open or close the shutter by means of the apparatus herein described,it is only necessary to turn the crank b and rotate the rod or shaft 1),thus operating the bent lever c by means of the gearing between them,the movement of the bent lever enabling the blind or shutter to beplaced and held at any desired point.

The device herein described is simple and efficient, and may be appliedto any shutter with greater facility than those heretofore known to me,and all the working parts being contained within the box derangementcaused by the action of the weather, &c., is entirely avoided.

, I design my shuttenworker for application more specially to framehouses, and so construct it as to obviate cutting or mortising the sillor other part of the window-frame. The box containing the gearing isapplied exteriorly of the building, beneath the sill, and the rods b andc are put in place through augerholes; and I do not claim, broadly, thecombination of worm-gearing arranged in a case and connected by a bentarm with the shutter, and operated through the gearing by a shaftextending through the side of the house into such house.

I am aware that a shutter having a rod attached to the casing, and uponwhich slides a sleeve pivoted to an arm secured to the axis of aworm-gear seated in a recess in a windowsill and turned by a worm, hasbeen employed; but such construction I do not herein claim.

I claim- The casing or box a, secured exterior-1y of the buildingbeneath the sill B, and containing the vertical worm-wheel e and meshingwormgear d, combined with the bent lever 0, having bearings in thecasing or box, and engaged by the wornrwheel, and connected to or withthe shutter, and the rod or shaft 5, extended through the side of thehouse and having bearings in the casing or box and engaging the worm tooperate it, all constructed and arranged substantially as shown anddescribed.

In testimony whereof I have signed my name to this specification in thepresenceof two subscribing witnesses.

HARDEN PALMER.
